Unsolved
Same as in Wallpaper_CB_Up_We_Go, however harder to isolate.
Wondering why it would be identical yet harder to isolate in a later image I set about isolating it as best I could.
I found that taking bit planes 0-3 for all the channels, inverting the 0th and 3rd planes, and then merging them with a multiply blend mode resulted in a nearly perfect isolation.
Doing so also left Robatama looking like a starry night sky:

1200131304171100: Mannerla

Breaking up the string into two digit substrings and using A0Z25 to convert the numbers to letters gives the solution:

Both Kari and Mannerla appeared as clues on their own, but this is the first location where they have been found combined.

Kari Mannerla (January 9, 1930, HelsinkiFinland – July 12, 2006, Helsinki, Finland) was a Finnish board and card game designer and advertising agency executive. The most famous game designed by Mannerla is the board game Afrikan tähti (The Star of Africa), the idea of which he began to develop in 1949. The game was published two years later. Mannerla made up the name of the game when reading an article about the biggest diamond in the world, the Star of Africa, discovered in South Africa.
